What Is a Falling Iguana Warning
A falling iguana warning is an alert issued by the National Weather Service when temperatures are forecast to drop low enough that cold-blooded iguanas may become temporarily immobile and fall from trees. The warning is specific to South Florida and similar subtropical areas where green iguanas are common.
When and Why Iguanas Fall
Iguanas become sluggish and lose grip when temperatures fall below about 40 to 50 degrees Fahrenheit. During cold snaps, they may fall from branches while sleeping. The warning is meant to alert residents to the possibility of encountering stunned or inactive iguanas on the ground, sidewalks, and in yards.
What to Do During a Falling Iguana Warning
Officials advise residents to give fallen iguanas space, avoid handling them, and keep pets away. Iguanas may appear dead but can recover once temperatures rise. The warning is not a threat to human safety, but it can affect landscaping, fences, and local wildlife management. For official guidance, see the National Weather Service.
